Hydraulic fittings

[TomA in CA]

I have a JinMa 354. I need to replace a control valve. The question I have is are the fittings standard sae or some proprietary Chinese fitting.

Which control valve?

If OEM you should be able to look it up in one of the online parts catalogs. Places like Circle G and Affordable have good online catalogs.

It is possible that the sizes will be listed in the catalog. If not you will have to pull a fitting and measure it.

Hydraulic places have some good info on how to measure the various "standards" used around the world. Discount Hydraulic is one such place.

My tractor has a mix of metric and SAE fittings. The loader has some metric and some DIN. You have to take the fittings apart to figure out what they are, no way to tell from the outside.

Nothing proprietary or Chinese about them, they are just metric O-ring - Face - Seal (ORFS) fittings. Used around the world.
